Least Privilege Security is the practice of assigning users and programs the minimum permissions required to complete a given task. Implementing this principle in different versions of Microsoft Windows requires careful planning and a good understanding of Windows security. While there are benefits in implementing Least Privilege Security on the desktop, there are many technical challenges that you will face when restricting privileges.

This book contains detailed step-by-step instructions for implementing Least Privilege Security on the desktop for different versions of Windows and related management technologies. It will provide you with quick solutions for common technical challenges, Microsoft best practice advice, and techniques for managing Least Privilege on the desktop along with details on the impact of Least Privilege Security.

The book begins by showing you how to apply Least Privilege Security to different categories of users. You will then prepare a desktop image with Least Privilege Security enabled from the start and deploy the new image while preserving users’ files and settings. You will identify problems with applications caused by Least Privilege Security using the Application Compatibility Toolkit. This book will help you configure User Account Control on multiple computers using Group Policy and support Least Privilege user accounts using reliable remote access. Then, you will modify legacy applications for Least Privilege Security, achieving the best balance between compatibility and security by using Application Compatibility shims. You will install per-machine ActiveX Controls using the ActiveX Installer Service (AxIS). The book will help you implement best practices for working with ActiveX Controls in a managed environment. Finally, you will deploy default Software Restriction Policy (SRP) or AppLocker rules to ensure only programs installed in protected locations can run and blacklist applications using SRP or AppLocker.

Chapter 1: An Overview of Least Privilege Security in Microsoft Windows Explore the principle of Least Privilege Security and implement it in different versions of Microsoft Windows. Control and change system privileges. Benefit from implementing Least Privilege Security on the desktop and overcome the most common technical and political problems and challenges when implementing Least Privilege Security.

Chapter 2: Political and Cultural Challenges for Least Privilege Security Understand the reasons why users may not accept Least Privilege Security on the desktop. Clearly explain and justify the benefits of Least Privilege Security for your organization. Apply Least Privilege Security to different categories of users and get buy-in from management.

Chapter 5: User Account Control Achieve a seamless user experience by using the different components and compatibility features of User Account Control. Configure User Account Control on multiple computers using Group Policy and understand the inner workings of User Account Control’s core components. OA Chapter 6: Supporting Users Running with Least-Privilege Support Least-Privilege user accounts using reliable remote access. Connect to remote systems with administrative privileges using different techniques. Enable remote access using Group Policy and Windows Firewall.

Chapter 7:Microsoft Windows Application Compatibility Infrastructure Modify incompatible applications on the fly and achieve the best balance between compatibility and security by using Application Compatibility shims. Create shims using Application Compatibility Toolkit 5.5 and distribute compatibility databases to devices across the enterprise.

Chapter 8: Software Distribution using Group Policy Prepare to deploy applications using Group Policy Software Installation (GPSI) and Windows Installer. Repackage legacy setup programs in Windows Installer .msi format. Make GPSI more scalable and flexible using the Distributed File System (DFS). Target client computers using Windows Management Instrumentation (WMI) filters and Group Policy Scope of Management.

Chapter 9: Internet Explorer Add-on Management Support per-user and per-machine ActiveX Controls and manage Internet Explorer add-ons via Group Policy. Install per-machine ActiveX Controls using the ActiveX Installer Service (AxIS). Implement best practices for working with ActiveX Controls in a managed environment.

Chapter 10: Software Restriction Policies and AppLocker Deploy default Software Restriction Policy (SRP) or AppLocker rules to ensure only programs installed in protected locations can run. Force an application to launch with standard user privileges even if the user is an administrator. Blacklist an application using SRP or AppLocker.
